What is the difference between the anhydrides of organic and inorganic acids

The anhydrides of organic and inorganic acids differ in multiple aspects, mainly as follows:
Formation method: Inorganic acids are formed by the direct loss of one molecule of water from the acid, resulting in the formation of its anhydride. The valence of the elements that determine acidity in the anhydride remains unchanged. Organic acids are formed by dehydration reactions between two or more molecules of the acid.
Property: The anhydrides of inorganic acids are usually formed by dehydration and condensation of acid molecules, and are mostly oxides, such as carbon dioxide (acid anhydrides) and dinitrogen pentoxide (nitrate anhydrides). Although organic acid anhydrides are also formed by dehydration and condensation of acid molecules, the compounds formed are not oxides, but also known as anhydrides, such as acetic anhydride and phthalic anhydride.
Application: Inorganic acid anhydrides have important applications in multiple fields, such as the use of carbon dioxide in industrial, medical, and other fields. Organic acid anhydrides such as acetic anhydride are mainly used in organic synthesis, dyes, pharmaceutical industry, and the manufacture of acetyl compounds.
Overall, there are significant differences in the formation mode, properties, and applications of organic and inorganic acid anhydrides. These differences stem from their different chemical structures and properties, making them applicable in various fields.
